Yes. We insist on having Swing in our applets, so we do it all the time.
Your URL:
`http://poppy.dev.lon.deuba.com:9090/pilgpe/servlet/com.db.docserv.servlet.A
dminServlet'
looks suspicious. By default, the servlet directory is usually virtualed to:
`http://poppy.dev.lon.deuba.com:9090/servlet/com.db.docserv.servlet.AdminSer
vlet'
Did you take care to make sure the virtual directory for the servlet engine
was set up correctly?
If you paste the URL directly into the browser, do you also get the file not
found exception?
Finally, your life will get interesting when you try to use session tracking
with the plugin configuration. Use URL rewriting for this.

Subject: HTTP Tunnelling + Applet + Java Plug1.3 + Servlets 2.0
Hi
Has anyone out there ever successfully coded applet/servlet combo that uses
HTTP
Tunnelling communication and works with the Java Plugin 1.3.
FWIW HTTP Tunnelling is sending a Java Object package encoded through
standard
HTTP output stream. In other words writing an Java object to
HTTPServletResponse
e.g.
void doPost( HttpServletRequest req, HttpServletResponse res)
{
res.setContentType("java-serialised/com.db.docserv.MenuItemNode" );
ObjectOutputStream out = new ObjectOutputStream( res.getOutputStream );
...
MenuItemNode node = new MenuItemNode( ... );
..
out.write( node );
out.flush();
out.close();
}
If I know that it (HTTP Tunnelling) works? Then I can eliminate the fault
being with Java
Plugin and look at the `com.oreilly.servlet.HttpMessage' class?
Last, when HTTP Tunnelling is used. Does the mime type in the servlet need
to be specific value?
What should it be ( `application/x-java-vm?' ) ?
Or even `application/x-java-vm/java-applet' ,
`application/com.db.docserv.MenuItemNode'
rom Jason Hunter's book?
Any help appreciated
